What makes it different from others?

The film makes a home in your brain and the only cure is to see it again.

if their story seems completely bonkers, almost like a feverish work of fiction, you ain't heard nothing yet.

If you're interested in the topic at hand, you should just watch it and judge yourself because the reviews have gone very biased by people that didn't even watch it and just hate (or love) the creator. I liked it, it was well written, narrated, and directed and it was about a topic that interests me.
